A simple Hugo partial template that renders a world coverage map using jVectorMap SVG library and dataset from Natural Earth.
I was never a huge fan of loading a fully featured map (like OpenStreetMap) to only show country level coverage info, that's why I was looking for simpler solutions and SVG based one is the best, light and fast, exactly what I need.
Without further due, you can see it in action in About page and play with the source code.
Happy travel!
